Do not worry! Three-trick to help you pick a good memory


Athlon64 and P4 platform has now completely universal, because lead users to upgrade the system memory bandwidth hungry, no less than the Chinese team won the Chinese fans desire. Therefore, the current level of DDR400 and above memory under unprecedented attention. This article is a particles from memory breakthrough, we recommend the memory by the excellent reputation of particles with high-quality parts and superior production quality memory modules.

The first one: the most important memory particles

First, the particle itself is good or bad quality of the quality of the memory modules is almost vital. Particles like a good girl to be married must have the same "after the name of the door" and "clean record" two conditions.

The so-called "well-born" is to be famous maker of memory particles. Although the use of brand-name manufacturers of memory particles do not necessarily represent the memory module is excellent, but the particles with unknown brand of memory is obviously not good performance. Now well-known brands of memory particles HY (modern), Samsung (Samsung), Winbond (Winbond), Infineon (Infineon), Micron (Micron) and so on. Brand-name manufacturers in the FAB, the in harsh conditions (constant temperature and humidity, no water, no electricity), and after long months of physical, chemical, optical reaction, only a qualified silicon wafer smooth birth. After the polymer and then relied on close cut, leaving only the highest quality performance in the middle part of the essence. Then selecting the essence of these "cream" of encapsulation. The next factory will be packaged particles rigorous testing. In the original tests, test equipment according to the procedure required to complete the testing process, consuming 600 to 800 seconds, test temperature of -10 ~ +85 degrees Celsius. During this testing process can guarantee a good compatibility particles (particle Compatibility determine the compatibility of memory) and durability (durability particles determines the memory overclocking capability and service life). As the chip-level test equipment is very expensive, and its life under the working time, and it is usually in seconds. So the testing process for the production cost greatly. Until the test, particles were allowed to be marked with quality and quality on behalf of the original Mark. Until here this "Name the door Young Lady" before becoming born.

By "etching printing" Winbond CH5 quality particles:

The so-called "clean record" is to ensure the particles represented by a symbol and consistent quality. Because some unscrupulous businessmen often the so-called OEM memory particles (derived from the above-mentioned silicon wafer scrap, and not through the original test of the secondary product particles) changed the original sign bogus "names the door Young Lady." Through careful observation of particles on the original signs are clear, whether the mill had to identify traces of authenticity.

Second, the quality of parts is also excellent memory modules can be to Make an indispensable condition. "A door feminist" only accompanied by a component of the dowry can "casual Chu Ge." High-quality PCB board for memory particles impact on the similar in stable and reliable motherboards with the role of the CPU.

The second measure: the selection of quality PCB

PCB is the fundamental quality of memory, we should try to select more layers, more thick PCB board. In fact, early in the specification in which Intel, the provisions of the memory must use the 6 layer PCB manufacturing, and on the PCB material, layer spacing, the thickness of deposited copper, circuit layout parameters, etc. have corresponding strict processing requirements.

6 layer PCB board, you can see the clear words of the Identity 6:



Second, PCB board should have as many chip resistors and capacitors, as thick cheat. When you board the purchase would be very concerned about the number of chip resistors and capacitors, and the number of welding process, the same high-quality memory modules in the use of chip resistors and capacitors is also no way slack.

Goldfinger's gold is an important indicator of quality to the commonly used Immersion gold process, gold layer thickness generally 3 to 5 microns, and high-quality memory gold thickness can reach 6 to 10 microns. Not easy to wear thick gold layer, and contacts can increase the antioxidant capacity, longer life. Recently appearing on the market, "Apacer gold medal," the cost of higher memory actually used electroplating technology, making cheat gold thickness of 20 microns.

The third measure of process quality from excellent

Memory manufacturing welding quality is very important factor. Cheap and reasonable welding process solder will have a lot of Weld, in a period of use, the gradual oxidation of the Weld joints may produce random failures. And this failure is difficult to confirm, so the event will give people the feeling of eating flies. This happens more often in the cottage factory "production line" on the production of memory appear. Kingston (Kingston), Apacer (Apacer), Transcend (create) and other well-known third-party memory module factory (that does not manufacture memory particles, just after the section of memory packaging and testing manufacturers) are based on the level of millions of dollars high-speed SMT machine, under the control of the computer program, to build a scientific and efficient memory modules, memory modules can effectively maintain the consistency of high quality.

Brand-name memory exquisite craft:

In addition, third-party memory modules original retail product launch, will have an independent anti-static packaging, as well as complete after-sales service, consumers of these products, they can spend less energy, more of a worry.
